Balance potentiometer for stepper drivers

Strange issue with the stepper drivers on a ramps. Its like there is not enough power to drive all the steppers, turning up one potentiometer to get that stepper running smoothly, seems to make another motor start to judder. I cant seem to find anyone having the same issue, how do I get them balanced?

I would venture to guess that the power supply / Supply wiring is not rated for the current.
This means that if you are pulling more power than the supply or wiring can handle something is going to be starving for energy.

When I assembled my first 3D Printer they gave me this tiny wire to run the controller, I used knowing it would not work.
While I was using the wire you could smell the heat, and when a multi-meter was used you could measure the voltage drop from the supply to the controller.
This voltage drop being almost 4 volts. Controller was tiring to function with 8 volts, this is not sufficient to operate the controller an caused printer to act incorrectly...

When the stepper starts doing that, maybe try holding the filament yourself by the extruder, release the extruder wheel pressure on the filament, and slowly push the filament through with your fingers, just to see if the filament path is not getting stuck somehow.

If not, then when it does that, just release the extruder's filament wheel pressure again and see if the stepper starts rotating normally.

Well this is now a different issue, I would have thought? I have balanced the power for the steppers. And then I opened a new post because, while its the same problem, cant extrude, its a new issue, its nothing to do with balancing the stepper drivers.
